What is PLC? What are you going to learn?

Hello. First of all, it is necessary to understand the knowledge of electricians, understand the control of electrical appliances, understand various actuators, and then understand the working mode of PLC, input and output circuits, and finally understand the corresponding process.

1. To learn PLC, we must first choose to learn which manufacturer's PLC, the Japanese PLC has a high degree of internal software integration, and the application is simple Early OMRON and Mitsubishi applications are more, and now due to the application of Siemens PLC and Rockwell due to the first and international partnerships, Rockwell is a little more, (although it is said that learning a brand is profound, others will soon get started, but people's energy is limited, and we must use limited energy in the most widely used, potential, and development direction, However, for each brand of PLC have some understanding, including imported, domestic, these have a corresponding understanding, for the characteristics of each PLC, advantages and disadvantages, these have a better understanding, then the future will be a rare talent in the market. ）

2. PLC is not a single programming technology, it is a system professional course. A PLC can be broadly considered as a high-reliability PC with an operating system embedded in the back. First of all, you need to be proficient in the programming language ladder diagram and statement table language of the PLC itself.

At this level, you can only read the programmed programs, and you can copy the programs needed to design some projects. In this industry, it is also necessary to apply VB and VC to realize serial port communication and distributed control system. Knowledge of databases is also required in some large programs.

PLC is quick to get started, but you have to keep making an effort to keep improving. ）

3. PLC is a discipline that focuses on the application direction. So a little more practice. Don't look down on small projects, where you can summarize the logical thinking method for designing programs.

Keep making progress in the summary. For example, every time you go to the site for debugging, you can call the program on the site to check it, and understand what are the differences and characteristics between the structure of the program and other programs, so that the progress will be faster.

PLC is a programmable logic controller.

It is a number-operated electronic clenching circle system designed for use in industrial environments. To put it bluntly, it is a program to control a certain object, and people don't have to do it in real time, in short, it is very convenient. Learning anything, is a certain degree of difficulty, when learning to walk is a little difficult, enough interest has been successful in the first step, you can try, usually read more information, now a lot of information on the Internet, a handful of people often go to "skills" to find, information, **, software have, I hope it will help you. Look ......

A kind of digital controller, to be studied in mechanical and electrical majors. Programming bars, over-control, etc.

Programmable logic controller, which uses a class of programmable memory for its internal storage programs, executes user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog input and output.

Basic computer operation, a certain electrical and electronic foundation is enough.

Of course, love and determination for PLCs are essential.

The use of PLC] PLC, and IPC, single-chip microcomputer are collectively known as the three pillars of industrial automation, and the current industrial automation control can be completed by PLC. PLC has become an indispensable part of industrial automation, it is widely used, because it is simple to use, good stability, more powerful, more moderate, programming is more convenient, it can be used in temperature, logic, humidity, pressure, specific quantity, calculation, man-machine and many other control systems, 80% of modern industry are controlled by PLC; At present, learning PLC well can make it very easy to find a well-paying job.

PLC] programmable logic controller, which uses a class of programmable memory for its internal storage programs, performs user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog input and output.

To make money, now there is almost no pure contactor control circuit in the factory electrical, all of which are replaced by PLC control, which reduces the intermediate control points and reduces the failure rate. Easy to find. So when you read it, give me all the points.
